The only problem with showing the source file is that it would be the
only 96k graph in the set. All the others are 44.1k downsampled
results. The change in the graph scale just might introduce slight
visual differences. They could also synthesize the expected 44.1k
result and graph that, although I have no idea how fair that it. I
guess the graphs are too low resolution to worry about this level of
detail.

The link that Bias cites as "matching our results" is much more

This shows clear aliasing in Bias Peak Pro 5.2, and I'm not sure
how the White Paper was able to hide this aliasing, even with their
color assignments. I like the way the Infinite Wave graphs look,
better than the prior Matlab ones.
I like that one better, too. It looks like it doesn't have a cutoff
on the low end (or it has a much lower cutoff). It's dead black
where all the others have a slight haze of dark blue (truncation
error). The only thing is they don't show the plot of the source file.
